dusting nor spraying lime sulphur alone 
will do any harm to the bees, as the 
lime sulphur is not poisonous, and, 
what is more, the bees will not go near 
trees that are not in bloom. 
DDT Our Friend Rather than Our Foe 
The appalling losses of bees from 
the use of arsenicals, as reported 
from all over the country, presented a 
problem that was difficult to solve. Up 
to recently nothing seemed to be as ef¬ 
fective as arsenic mixed with other 
poisons in the form of a spray or a 
dust. In either case a rain would wash 
off the poisons making it necessary to 
apply fresh amounts of arsenate of 
lead, and often there seemed to be no 
hope in sight until recently, and that 
hope came from the most powerful in¬ 
secticide the world has ever known. 
Strange as it may seem, it is apparent 
from the evidence at hand that DDT 
will, to a large extent, displace arsen¬ 
icals that have been causing the awful 
destruction of bees, sometimes result¬ 
ing in controversies and lawsuits be¬ 
tween beekeepers, farmers, and fruit 
growers. 
Late work in the laboratory and in 
the field is piling up showing almost 
conclusively that both the horticultur- 
alists and the beekeepers will welcome 
the use of DDT. While it will kill bees 
when confined in cages or in beehives, 
either in the form of a spray or dust, 
it has now been pretty well proven 
that DDT, when properly applied, un¬ 
der field conditions, is far less destruc¬ 
tive to bees and other pollinating in¬ 
sects than the arsenicals which require 
frequent applications to make them 
effective. Recent tests made by Ed-
